It combines a microcontroller-driven control circuit with low-resistance MOSFET switching so devices are safeguarded without wasting energy; RGB LED indication and a three-position rocker give clear status and flexible control.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the LVD protect my battery during long outages?\u003c\/h3\u003e\n\u003cp\u003eSet the module to AUTO and program a cutoff (disconnect) voltage and a reconnect voltage. If battery voltage falls to or below the disconnect threshold for five continuous seconds, the module opens the load circuit; when voltage rises to the reconnect level for five continuous seconds, it closes again. This prevents deep discharge cycles that shorten battery life.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable disconnect\/reconnect thresholds for precise protection\u003c\/li\u003e\n  \u003cli\u003e5-second debounce to avoid accidental switching from brief transients\u003c\/li\u003e\n  \u003cli\u003eAutomatic reconnection when sufficient charge returns\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat settings and user controls are available?\u003c\/h3\u003e\n\u003cp\u003eThe LVD uses a rocker switch with three positions: AUTO for programmable operation, ON to force the output closed, and OFF to force the output open. In AUTO mode you program the disconnect and reconnect voltages; ON\/OFF modes give immediate and persistent control for emergency situations or testing.
